Map of USGS gauge 01454700 and the river around it
Where Lehigh River at Glendon, PA sits, with 3 other gauges on the same river.
In or under PFBC's preferred range. Water 57°F now; the highest in the last 24 hours was 57.2°F. The Pennsylvania Fish and Boat Commission: “The preferred temperature range for trout is between 50 and 60 degrees Fahrenheit.”
Normal for Nov 5: 986–2,720 ft³/s (middle half of 47 years of record). Now: 836 ft³/s, below normal.
Below normal for this date. 836 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 47 years of record (1967–2026): 10th 763, 25th 986, median 1,940, 75th 2,720, 90th 4,310 ft³/s.
Daily means on record for Nov 5: lowest 590 ft³/s, highest 8,050 ft³/s.
Classes as USGS labels them (hyswap: flow categories (WDFN_stats schema) (U.S. Geological Survey) ); percentiles from the USGS daily statistics (U.S. Geological Survey) (approved daily means; the reading is provisional and instantaneous).
Steady over 24 hours (+4.4% discharge). Rising or falling means a change of more than 10% in discharge (or 0.2 ft of gauge height) over 24 hours; our rule of thumb, not a USGS class.
Species list not on file for this gauge. Check the Pennsylvania Fish and Boat Commission: Pennsylvania adult trout stocking schedule · Pennsylvania fishing regulations.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
Flood categories: action stage, minor, moderate and major flooding (National Weather Service)Cold water. Water 57°F. NWS: “Cold shock can be just as severe and dangerous from water temperatures of 50-60°F (10-15°C) as it is from water at 35°F (2°C).” “Always wear a life jacket in and around the water.”
Cold Water Hazards and Safety (National Weather Service)Turn Around Don't Drown. “A mere 6 inches of fast-moving flood water can knock over an adult.” No flow number makes a crossing safe; if in doubt, stay out.
Turn Around Don't Drown (National Weather Service)Dissolved oxygen 8.6 mg/L at Nov 5, 8:45 PM EST; 7-day range 7.5–11.7 mg/L
Enough oxygen for coldwater fish: 8.6 mg/L meets the 6.5 mg/L EPA sets for coldwater fish (other life stages; eggs and fry need a 8 mg/L minimum).
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)pH 7.6 at Nov 5, 8:45 PM EST; 7-day range 7.5–8
Within EPA's freshwater range: pH 7.6 is within the 6.5–9 range EPA gives for freshwater aquatic life.
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)Specific conductance 371 µS/cm at Nov 5, 8:45 PM EST; 7-day range 347–435 µS/cm
Dissolved ions: Specific conductance rises with the ions dissolved in the water. No fishing threshold is published for it; compare with this gauge's own recent readings.
Conductivity (Electrical Conductance) and Water (U.S. Geological Survey)Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
NWS observed 7.2 ft stage, 827 ft³/s at Nov 5, 7:45 PM EST (NWS gauge GLDP1; its stage datum can differ from the USGS gauge height).
Forecasts are not available. Only observed stages are available for this point.
